A British woman has been arrested on Indonesia's resort island of Bali for allegedly smuggling $2.5 million worth of cocaine in her luggage. If found guilty, she faces a maximum penalty of death by firing squad.

Customs official Made Wijaya told reporters Monday that 56-year-old arrived on a flight from Bangkok on May 19. He said 4.7 kilograms (10.36 pounds) of cocaine were seized from her suitcase.

Three other Britons and an Indian national were believed to be the intended recipients. They are being questioned.

Indonesia has extremely strict drug laws and convicted smugglers are executed. More than 140 people are on death row, a third of them foreigners.
